| 1st row | A fully differential calculation in perturbative quantum chromodynamics is presented for the production of massive photon pairs at hadron colliders. All next-to-leading order perturbative contributions from quark-antiquark, gluon-(anti)quark, and gluon-gluon subprocesses are included, as well as all-orders resummation of initial-state gluon radiation valid at next-to-next-to-leading logarithmic accuracy. The region of phase space is specified in which the calculation is most reliable. Good agreement is demonstrated with data from the Fermilab Tevatron, and predictions are made for more detailed tests with CDF and DO data. Predictions are shown for distributions of diphoton pairs produced at the energy of the Large Hadron Collider (LHC). Distributions of the diphoton pairs from the decay of a Higgs boson are contrasted with those produced from QCD processes at the LHC, showing that enhanced sensitivity to the signal can be obtained with judicious selection of events. |

| 2nd row | We describe a new algorithm, the $(k,\ell)$-pebble game with colors, and use it obtain a characterization of the family of $(k,\ell)$-sparse graphs and algorithmic solutions to a family of problems concerning tree decompositions of graphs. Special instances of sparse graphs appear in rigidity theory and have received increased attention in recent years. In particular, our colored pebbles generalize and strengthen the previous results of Lee and Streinu and give a new proof of the Tutte-Nash-Williams characterization of arboricity. We also present a new decomposition that certifies sparsity based on the $(k,\ell)$-pebble game with colors. Our work also exposes connections between pebble game algorithms and previous sparse graph algorithms by Gabow, Gabow and Westermann and Hendrickson. |
| 3rd row | The evolution of Earth-Moon system is described by the dark matter field fluid model proposed in the Meeting of Division of Particle and Field 2004, American Physical Society. The current behavior of the Earth-Moon system agrees with this model very well and the general pattern of the evolution of the Moon-Earth system described by this model agrees with geological and fossil evidence. The closest distance of the Moon to Earth was about 259000 km at 4.5 billion years ago, which is far beyond the Roche's limit. The result suggests that the tidal friction may not be the primary cause for the evolution of the Earth-Moon system. The average dark matter field fluid constant derived from Earth-Moon system data is 4.39 x 10^(-22) s^(-1)m^(-1). This model predicts that the Mars's rotation is also slowing with the angular acceleration rate about -4.38 x 10^(-22) rad s^(-2). |
| 4th row | We show that a determinant of Stirling cycle numbers counts unlabeled acyclic single-source automata. The proof involves a bijection from these automata to certain marked lattice paths and a sign-reversing involution to evaluate the determinant. |
| 5th row | In this paper we show how to compute the $\Lambda_{\alpha}$ norm, $\alpha\ge 0$, using the dyadic grid. This result is a consequence of the description of the Hardy spaces $H^p(R^N)$ in terms of dyadic and special atoms. |

All\nnext-to-leading order perturbative contributions from quark-antiquark,\ngluon-(anti)quark, and gluon-gluon subprocesses are included, as well as\nall-orders resummation of initial-state gluon radiation valid at\nnext-to-next-to-leading logarithmic accuracy. The region of phase space is\nspecified in which the calculation is most reliable. Good agreement is\ndemonstrated with data from the Fermilab Tevatron, and predictions are made for\nmore detailed tests with CDF and DO data. Predictions are shown for\ndistributions of diphoton pairs produced at the energy of the Large Hadron\nCollider (LHC). Distributions of the diphoton pairs from the decay of a Higgs\nboson are contrasted with those produced from QCD processes at the LHC, showing\nthat enhanced sensitivity to the signal can be obtained with judicious\nselection of events.\n | [{'version': 'v1', 'created': 'Mon, 2 Apr 2007 19:18:42 GMT'}, {'version': 'v2', 'created': 'Tue, 24 Jul 2007 20:10:27 GMT'}] | 2008-11-26 | [[Balázs, C., ], [Berger, E.

Numerical methods were devised to calculate\nresponse to shock and ramp compression, and ramp decompression, generalizing\nprevious solutions for scalar equations of state. The numerical methods were\nfound to be flexible and robust, and matched analytic results to a high\naccuracy. The basic ramp and shock solution methods were coupled to solve for\ncomposite deformation paths, such as shock-induced impacts, and shock\ninteractions with a planar interface between different materials. These\ncalculations capture much of the physics of typical material dynamics\nexperiments, without requiring spatially-resolving simulations.

We then discuss\nthe properties of the resulting high confidence set of YSO's. We find 235 such\nobjects in the 0.85 deg^2 field that was covered with both IRAC and MIPS. An\nadditional set of 51 lower confidence YSO's outside this area is identified\nfrom the MIPS data combined with 2MASS photometry. We describe two sets of\nresults, color-color diagrams to compare our observed source properties with\nthose of theoretical models for star/disk/envelope systems and our own modeling\nof the subset of our objects that appear to be star+disks. These objects\nexhibit a very wide range of disk properties, from many that can be fit with\nactively accreting disks to some with both passive disks and even possibly\ndebris disks. We find that the luminosity function of YSO's in Serpens extends\ndown to at least a few x .001 Lsun or lower for an assumed distance of 260 pc.\nThe lower limit may be set by our inability to distinguish YSO's from\nextra-galactic sources more than by the lack of YSO's at very low luminosities.\nA spatial clustering analysis shows that the nominally less-evolved YSO's are\nmore highly clustered than the later stages and that the background\nextra-galactic population can be fit by the same two-point correlation function\nas seen in other extra-galactic studies.
